Viper Level - As a stand alone, one might ask- why a Dodge Viper for a level? Its a good question. A Land rover or a Hum V would be a better choice. The reason is interaction. A series of sports cars that interact with a ramp truck have a common theme. They are all sports cars that can be carried by the ramp truck. The really fast cars have such a low ground clearance that they need to ride on a level surface anyway.
